Maybe so as far as getting mail delivered. But if you call a plumber because your drain line is overgrown with tree roots; Or you call a roofer because it's raining and you have a leak. Do you tell them to come to your PO box?
123 W 5th St
PO Box 11
Anytown WV
Or is there an actual address you give so the plumber can find you?
As far as a full timer it sounds like a pain that is coming down the line because of anti terrorism regulations. I wonder how the bank validates the physical address is actually your address and not something like the nearest small town store or something.
